“Subsidiary” shall include only an entity that qualifies under Section 424(f) of the Code as a “subsidiary corporation” with respect to the Company. 

3. Administration. 
 3.1
Administration. The Plan shall be administered by the Board or, to the extent authorized by the Board, the Committee. Either such entity shall have the right, from time to time, to delegate to one or more officers of the Company the authority
to grant and determine the terms and conditions of Awards granted under the Plan, subject to the requirements of applicable law and such other limitations as the Board or Committee, as applicable, shall determine. Either such entity shall also be
permitted to delegate, to any appropriate officer or employee of the Company, responsibility for performing certain ministerial functions under the Plan. In the event that the Board or Committee’s authority, as applicable, is delegated to
officers or employees in accordance with the foregoing, all provisions of the Plan relating to the Board or Committee shall be interpreted in a manner consistent with the foregoing by treating any such reference as a reference to such officer or
employee for such purpose. Any action undertaken in accordance with the proper delegation of authority hereunder shall have the same force and effect as if such action was undertaken directly by the Board or Committee, as applicable, and shall be
deemed for all purposes of the Plan to have been taken by the Board or Committee, as applicable. 
 3.2 Authority. Any authority of
the Committee may also be exercised by the Board (and any references to the Committee shall also be interpreted to refer to the Board), except to the extent that the grant or exercise of such authority would cause any Award or transaction to become
subject to (or lose an exemption under) the short-swing profit recovery provisions of Section 16 of the Exchange Act or fail to comply with applicable rules or regulations promulgated by any national securities exchange or national securities
association on which the Common Stock may be traded. The Committee shall have such powers and authority as may be necessary or appropriate for the Committee to carry out its functions as described in the Plan. Subject to the express limitations of
the Plan, the Committee shall have authority in its discretion to determine the Eligible Persons to whom, and the time or times at which, Awards may be granted, the number and type of shares or units subject to each Award, the purchase price of an
Award (if any), the time or times at which an Award will become vested, exercisable or payable, the performance criteria, performance goals and other conditions of an Award, the duration of the Award, and all other terms of the Award. The Committee
has the ability to set performance goals based on such metrics as it deems appropriate, including, but not limited to, non-GAAP performance measures included in any of the Company’s Securities and
Exchange Commission filings, operational metrics, financial ratios, total shareholder return, market share, line items on the Company’s balance sheet, and line items on the Company’s income statement. Subject to the terms of the Plan, the
Committee shall have the authority to amend the terms of an Award in any manner that is not 

  
 4 












 
inconsistent with the Plan, provided that no such action shall materially adversely affect the rights of a Participant with respect to an outstanding Award without the Participant’s consent.
The Committee shall also have discretionary authority to interpret the Plan, to make all factual determinations under the Plan, and to make all other determinations necessary or advisable for Plan administration, including, without limitation, to
correct any defect, to supply any omission or to reconcile any inconsistency in the Plan or any Award Agreement hereunder. The Committee may prescribe, amend, and rescind rules and regulations relating to the Plan. The Committee’s
determinations under the Plan need not be uniform and may be made by the Committee selectively among Participants and Eligible Persons, whether or not such persons are similarly situated. The Committee shall, in its discretion, consider such factors
as it deems relevant in making its interpretations, determinations and actions under the Plan including, without limitation, the recommendations or advice of any officer or employee of the Company or such attorneys, consultants, accountants or other
advisors as the Committee may select. All interpretations, determinations, and actions by the Board or the Committee, as applicable, shall be final, conclusive, and binding upon all parties. 

3.3 Liability & Indemnification. The Board, the Committee and their respective designees shall not be liable for
any action or determination made in good faith with respect to the Plan or any Award issued hereunder. The Company will indemnify and defend the Board, the Committee or their respective designees to the maximum extent permitted by law for all
actions taken on behalf of the Company with respect to the Plan. 
 4. Shares Subject to the Plan. 

4.1 Number of Shares Reserved. As of the effective time of the Merger and subject to adjustment pursuant to Section 4.2 hereof,
the maximum number of shares of Common Stock that may be issued under all Awards granted to Participants under the Plan shall equal 924,351, which reflects the sum of (a) the shares of Common Stock issuable pursuant to outstanding Awards
under the Plan immediately following the Merger and (b) the shares of Common Stock remaining available for the grant of new Awards under the Plan immediately following the Merger, each as determined by reference to the Exchange Ratio as defined
and set forth in the Merger Agreement. As of the effective time of the Merger and subject to adjustment as provided in Section 4.2 hereof: (a) the maximum number of shares of Common Stock with respect to which Incentive Stock Options may
be granted under the Plan shall be 924,351 shares; (b) unless otherwise determined by the Committee, the maximum number of shares of Common Stock with respect to which Awards may be granted to any single Participant in respect of any
single calendar year (including, without limitation, as a portion of any applicable performance period) shall be 275,000 shares; and (c) the maximum number of shares of Common Stock with respect to which Awards may be granted to any single non-employee member of the Board in any single calendar year (including, without limitation, as a portion of any applicable performance period) shall be 44,000 shares, each as determined by reference to the Exchange
Ratio as defined and set forth in the Merger Agreement. 
 4.2 Adjustments. If there shall occur any change with respect to the
outstanding shares of Common Stock by reason of any recapitalization, reclassification, stock dividend, extraordinary cash or stock dividend, stock split, reverse stock split, or other distribution or payment with respect to the shares of Common
Stock or any merger, reorganization, consolidation, combination, spin-

  
 5 












 
off, or other similar corporate change, or any other change affecting the Common Stock the Committee shall, in the manner and to the extent it considers in good faith to be equitable to the
Participants and consistent with the terms of the Plan, cause an adjustment to be made to (a) the number and kind of shares or units subject to Awards under the Plan pursuant to Section 4.1 hereof, (b) the number and kind of shares of
Common Stock or other rights (including, without limitation, cancellation of the awards in exchange for a cash payment or awarding cash payments to holders of such Awards) subject to then outstanding Awards, (c) the exercise price or base price
for each share or other right subject to then outstanding Awards, and (d) any other terms of an Award that are affected by the event or change. Notwithstanding the foregoing, (i) any such adjustments shall, to the extent necessary, be made
in a manner consistent with the requirements of Section 409A of the Code, and (ii) in the case of Incentive Stock Options, any such adjustments shall, to the extent practicable, be made in a manner consistent with the requirements of
Section 424(a) of the Code. 
 4.3 Availability of Certain Shares. Any shares of Common Stock covered by an Award granted under
the Plan shall not be counted unless and until they are actually issued and delivered to a Participant and, therefore, the total number of shares of Common Stock available under the Plan as of a given date shall not be reduced by shares of Common
Stock relating to prior Awards that (in whole or in part) have expired or have been forfeited or cancelled, and upon payment in cash of the benefit provided by any Award, any shares of Common Stock that were covered by such Award will be available
for issue hereunder. For the avoidance of doubt, the following shares of Common Stock shall again be made available for delivery to Participants under the Plan: (a) shares of Common Stock not issued or delivered as a result of the net
settlement of an outstanding Stock Option, (b) shares of Common Stock used to pay the exercise price or withholding taxes related to an outstanding Award, (c) shares of Common Stock repurchased by the Company using proceeds realized by the
Company in connection with a Participant’s exercise of a Stock Option, and (d) shares of Common Stock purchased by Participants for Fair Market Value. 

5. Eligibility and Awards. Any Eligible Person may be selected by the Committee to receive an Award and become a Participant under the Plan. The
Committee has the authority, in its discretion, to determine and designate from time to time those Eligible Persons who are to be granted Awards, the types of Awards to be granted, the number of shares of Common Stock subject to Awards to be granted
and the terms and conditions of such Awards consistent with the terms of the Plan. In selecting Eligible Persons to be Participants, and in determining the type and amount of Awards to be granted under the Plan, the Committee shall consider any and
all factors that it deems relevant or appropriate. 
 6. Stock Options. 

6.1 Grant of Stock Options. A Stock Option may be granted to any Eligible Person selected by the Committee. Subject to the provisions
of Section 6.6 hereof and Section 422 of the Code, each Stock Option shall be designated, in the discretion of the Committee, as an Incentive Stock Option or as a Nonqualified Stock Option. 

6.2 Exercise Price. The exercise price per share of a Stock Option shall not be less than 100% of the Fair Market Value of the shares
of Common Stock on the Date of Grant. The Committee may, in its discretion, specify for any Stock Option an exercise price per share that is higher than the Fair Market Value on the Date of Grant. 

  
 6 












 6.3 Vesting of Stock Options. The Committee shall in its discretion prescribe the
time or times at which, or the conditions upon which, a Stock Option or portion thereof shall become vested and/or exercisable. The requirements for vesting and exercisability of a Stock Option may be based on the continued Service of the
Participant, on the attainment of specified performance goals or on such other terms and conditions as approved by the Committee in its discretion. The vesting and exercisability of a Stock Option may be accelerated by, and may be dependent upon, in
whole or in part, the occurrence of a Qualified Liquidity Event. 
 6.4 Term of Stock Options. The Committee shall, in its
discretion, prescribe in an Award Agreement the period during which a vested Stock Option may be exercised, provided, however, that the maximum term of a Stock Option shall be ten years from the Date of Grant. A Stock Option may be earlier
terminated as specified by the Committee and set forth in an Award Agreement upon or following the termination of a Participant’s Service with the Company or any Subsidiary. 

6.5 Stock Option Exercise; Tax Withholding. Subject to such terms and conditions as specified in an Award Agreement, a vested Stock
Option may be exercised in whole or in part at any time during the term thereof by notice in the form required by the Company, together with payment of the aggregate exercise price therefore, provided that arrangements satisfactory to the Company
have been made with respect to any applicable withholding tax, pursuant to Section 13.4 hereof. Payment of the exercise price shall be made in one or more of the following forms of payment at the election of the Participant: (i) in cash or
by cash equivalent acceptable to the Committee, (ii) to the extent permitted by the Committee in its discretion, in shares of Common Stock, valued at the Fair Market Value of such shares on the date of exercise, (iii) to the extent
permitted by the Committee in its discretion, by reduction in the number of shares of Common Stock otherwise deliverable upon exercise of such Stock Option with a Fair Market Value equal to the aggregate exercise price of such Stock Option at the
time of exercise, (iv) to the extent permitted by the Committee in its discretion, by a combination of the foregoing methods, or (v) by such other method as may be approved by the Committee or set forth in the Award Agreement. 

6.6 Additional Rules for Incentive Stock Options. 

(a) Eligibility. An Incentive Stock Option may be granted only to an Eligible Person who is considered an employee for
purposes of Treasury Regulation §1.421-7(h) with respect to the Company or any Subsidiary that qualifies as a “subsidiary corporation” with respect to the Company for purposes of
Section 424(f) of the Code. 
 (b) Annual Limits. No Incentive Stock Option shall be granted to a Participant as
a result of which the aggregate Fair Market Value (determined as of the Date of Grant) of Common Stock with respect to which incentive stock options under Section 422 of the Code are exercisable for the first time in any calendar year under the
Plan and any other stock option plans of the Company or any subsidiary or parent corporation, would exceed $100,000, determined in accordance with Section 422(d) of the Code. This limitation shall be applied by taking stock options into account
in the order in which they were granted. 
 (c) Termination of Employment. An Award of an Incentive Stock Option may
provide that such Stock Option may be exercised not later than three months following 

  
 7 












 
termination of employment of the Participant with the Company and all Subsidiaries, or not later than one year following a permanent and total disability within the meaning of
Section 22(e)(3) of the Code, as and to the extent determined by the Committee to comply with the requirements of Section 422 of the Code. 

(d) Other Terms and Conditions; Nontransferability. Any Incentive Stock Option granted hereunder shall contain such
additional terms and conditions, not inconsistent with the terms of the Plan, as are deemed necessary or desirable by the Committee, which terms, together with the terms of the Plan, shall be intended and interpreted to cause such Incentive Stock
Option to qualify as an “incentive stock option” under Section 422 of the Code. An Award Agreement for an Incentive Stock Option may provide that such Stock Option shall be treated as a Nonqualified Stock Option to the extent that
certain requirements applicable to “incentive stock options” under the Code shall not be satisfied. An Incentive Stock Option shall by its terms be nontransferable other than by will or by the laws of descent and distribution, and shall be
exercisable during the lifetime of a Participant only by such Participant. 
 (e) Disqualifying Dispositions. If
shares of Common Stock acquired by exercise of an Incentive Stock Option are disposed of within two years following the Date of Grant or one year following the transfer of such shares to the Participant upon exercise, the Participant shall, promptly
following such disposition, notify the Company in writing of the date and terms of such disposition and provide such other information regarding the disposition as the Company may reasonably require. 

7. Restricted Stock Awards. 
 7.1
Grant of Restricted Stock Awards. A Restricted Stock Award may be granted to any Eligible Person selected by the Committee. The Committee may require the payment by the Participant of a specified purchase price in connection with any
Restricted Stock Award. The Committee may provide in an Award Agreement for the payment of dividends and distributions to the Participant at such times as paid to stockholders generally or at the times of vesting or other payment of the Restricted
Stock Award. 
 7.2 Vesting Requirements. The restrictions imposed on shares granted under a Restricted Stock Award shall lapse in
accordance with the vesting requirements specified by the Committee in the Award Agreement. The requirements for vesting of a Restricted Stock Award may be based on the continued Service of the Participant, on the attainment of specified performance
goals or on such other terms and conditions as approved by the Committee in its discretion. The vesting of a Restricted Stock Award may be accelerated by, and may be dependent upon, in whole or in part, the occurrence of a Qualified Liquidity Event.

 7.3 Rights as Shareholder. Subject to the foregoing provisions of the Plan and the applicable Award Agreement, unless otherwise
prohibited by applicable law or determined by the Committee, the Participant shall have the rights of a shareholder with respect to the shares granted to the Participant under a Restricted Stock Award, including but not limited to the right to vote
the shares and receive all dividends in respect of shares and other distributions paid or made with respect thereto. Any Common Stock or other securities or payments received or payable as a 

  
 8 












 
dividend, distribution or otherwise will be subject to the same restrictions as the underlying Restricted Stock Award. 

7.4 Section 83(b) Election. If a Participant makes an election pursuant to Section 83(b) of the Code with respect to a Restricted
Stock Award, the Participant shall reasonably promptly provide a copy to the Company. The Committee may provide in an Award Agreement that the Restricted Stock Award is conditioned upon the Participant’s making or refraining from making an
election with respect to the Award under Section 83(b) of the Code. 
 8. Restricted Stock Unit Awards. 

8.1 Grant of Restricted Stock Unit Awards. A Restricted Stock Unit Award may be granted to any Eligible Person selected by the
Committee. The Committee may require the payment by the Participant of a specified purchase price in connection with any Restricted Stock Unit Award. 

8.2 Payment. A Restricted Stock Unit Award may be settled by the delivery of shares of Common Stock or their cash equivalent, any
combination thereof, or in any other form of consideration, as determined by the Committee and contained in the Award Agreement. 
 8.3
Vesting Requirements. The restrictions or conditions imposed on shares granted under a Restricted Stock Unit Award shall lapse in accordance with the vesting requirements specified by the Committee in the applicable Award Agreement. The
requirements for vesting of a Restricted Stock Unit Award may be based on the continued Service of the Participant, on the attainment of specified performance goals or on such other terms and conditions as approved by the Committee in its
discretion. The vesting and/or settlement of a Restricted Stock Unit Award may be accelerated by, and may be dependent upon, in whole or in part, the occurrence of a Qualified Liquidity Event. At the time of the grant of a Restricted Stock Unit
Award, the Committee, as it deems appropriate, may impose such restrictions or conditions that delay the settlement of a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award, subject to Section 409A of the
Code. 
 8.4 No Rights as Shareholder. Unless and until shares of Common Stock underlying a Restricted Stock Unit Award are actually
delivered to the Participant upon settlement of the Restricted Stock Unit Award, the Participant shall have no rights of a shareholder with respect to the shares granted to the Participant under a Restricted Stock Unit Award, including but not
limited to the right to vote the shares or receive dividends or other distributions or amounts accrued, paid or made with respect thereto. 

8.5 Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Common Stock covered by a Restricted Stock Unit
Award, as determined by the Committee and contained in the applicable Award Agreement. At the sole discretion of the Committee, such dividend equivalents may be converted into additional shares of Common Stock covered by the Restricted Stock Unit
Award in such manner as determined by the Committee. Any such dividend equivalents (including but not limited to any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents) will be subject to all
of the same 

  
 9 












 
terms and conditions of the underlying Award Agreement to which they relate, including, without limitation, with respect to the vesting and settlement thereof. 

9. Other Awards. An Other Award may be granted to any Eligible Person selected by the Committee. Subject to the terms of the Plan, the Committee will
determine the terms and conditions of any such Other Award, including but not limited to the price, if any, at which securities may be purchased pursuant to any Other Award granted under the Plan, and any applicable vesting, settlement and payment
terms. 
 10. Forfeiture Events. 
 10.1
General. The Committee may specify in an Award Agreement that the Participant’s rights, payments and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment (including, without limitation,
repayment to the Company of any gain related to the Award), or other provisions intended to have a similar effect, upon such terms and conditions as may be determined by the Committee, upon the occurrence of certain specified events, in addition to
any otherwise applicable vesting or performance conditions of an Award. Such events shall include, but shall not be limited to, termination of the Participant’s Service for Cause, the Participant’s violation of material Company policies or
breach of noncompetition, confidentiality or other restrictive covenants that may apply to the Participant. In addition, notwithstanding anything in the Plan to the contrary, any Award Agreement may also provide for the reduction, cancellation,
forfeiture or recoupment of an Award (including, without limitation, repayment to the Company of any gain related to the Award), or other provisions intended to have a similar effect, upon such terms and conditions as may be required by the
Committee or under Section 10D of the Exchange Act and any applicable rules or regulations promulgated by the Securities and Exchange Commission or any national securities exchange or national securities association on which the Common Stock
may be traded or under any clawback or similar policy adopted by the Company. 
 10.2 Termination for Cause. 

(a) General. Unless otherwise set forth in an Award Agreement or a written employment agreement between a Participant
and the Company, if applicable, if a Participant’s Service with the Company or any Subsidiary shall be terminated for Cause, such Participant’s rights, payments and benefits with respect to an Award shall be subject to cancellation,
forfeiture and/or recoupment. The Company shall have the power, subject to Section 10.2(b), to determine whether the Participant has been terminated for Cause and the date upon which such termination for Cause occurs. Any such determination
shall be final, conclusive and binding upon the Participant. In addition, if the Company shall reasonably determine that a Participant has committed or may have committed any act which is reasonably likely to constitute the basis for a termination
of such Participant’s Service for Cause, the Company may suspend for up to 30 days the Participant’s rights to exercise any option, receive any payment or vest in any right with respect to any Award pending a determination by the Company
of whether an act has been committed which is reasonably likely to constitute the basis for a termination for Cause as provided in this Section 10.2, but, in each case, only to the extent that such action would not result in an acceleration of
income or imposition of a tax under Section 409A of the Code. If, 

  
 10 












 
subsequent to a Participant’s voluntary termination of Service or involuntary termination of Service without Cause, it is discovered that the Participant’s Service could have been
terminated for Cause, the Committee may deem such Participant’s Service to have been terminated for Cause. 
 (b)
Definition of “Cause”. For purposes of the Plan and determining the treatment of Awards granted thereunder, unless otherwise provided in an applicable Award Agreement or as set forth in a written employment agreement between a
Participant and the Company, “Cause” shall mean: (i) the Participant’s commission of theft, embezzlement, any other act of dishonesty relating to Participant’s employment or service, or any willful violation of any law,
rules or regulation applicable to the Company, including, but not limited to, those laws, rules or regulations established by the Securities and Exchange Commission, or any self-regulatory organization having jurisdiction or authority over
Participant or the Company; or (ii) Participant’s conviction of, or plea of guilty or nolo contendere to, any felony or of any other crime involving fraud, dishonesty or moral turpitude; or (iii) a determination by the Company that
Participant has materially breached the terms of any agreement between Participant and the Company or any subsidiary of the Company; or (iv) Participant’s willful failure to perform the reasonable and customary duties of Participant’s
position with the Company or any subsidiary of the Company, which failure is not remedied within ten (10) business days after written demand by the Company for substantial performance is received by Participant which specifically identifies the
nature of such failure. 
 11. Restrictions on Transfer. Awards under the Plan shall not be assignable or transferable by the Participant, except by
will or by the laws of descent and distribution, and shall not be subject in any manner to assignment, alienation, pledge, encumbrance or charge. Notwithstanding the foregoing, in the event of the death of the Participant, except as otherwise
provided in an applicable Award Agreement, an outstanding Award may become payable to the Participant’s beneficiary as designated by the Participant in the manner prescribed by the Committee or, in the absence of an authorized beneficiary
designation, by the a legatee or legatees of such Award under the Participant’s last will, or by the Participant’s executors, personal representatives or distributees of such Award in accordance with the Participant’s will or the laws
of descent and distribution. Notwithstanding the foregoing, the Participant may, with the prior written consent of the Committee, make transfers of outstanding Awards to immediate family members or to a trust, the sole beneficiaries of which are the
Participant or immediate family members, in each case solely for estate planning purposes, in all instances subject to compliance with any applicable spousal consent requirements and all other applicable laws. 

12. General Provisions. 
 12.1 Award
Agreement. To the extent deemed necessary by the Committee, an Award under the Plan shall be evidenced by an Award Agreement in a written or electronic form approved by the Committee setting forth the number of shares of Common Stock subject to
the Award, the purchase price of the Award (if any), the time or times at which an Award will become vested, exercisable or payable and the term of the Award. The Award Agreement may also set forth the effect on an Award of a Qualified Liquidity
Event and a termination of Service under certain circumstances. The Award Agreement shall be subject to and incorporate, by reference or 

  
 11 












 
otherwise, all of the applicable terms and conditions of the Plan, and may also set forth other terms and conditions applicable to the Award as determined by the Committee consistent with the
limitations of the Plan. An Award Agreement may be in the form of an agreement to be executed by both the Participant and the Company (or an authorized representative of the Company) or certificates, notices or similar instruments as approved by the
Committee. The Committee need not require the execution of an Award Agreement by a Participant, in which case, acceptance of the Award by the Participant shall constitute agreement by the Participant to the terms, conditions, restrictions and
limitations set forth in the Plan and the Award Agreement. 
 12.2 Determinations of Service. Subject to applicable law, including
without limitation Section 409A of the Code, the Committee shall, in good faith, make all determinations relating to the Service of a Participant with the Company or any Subsidiary in connection with an Award, including, without limitation,
with respect to the continuation, suspension or termination of such Service. A Participant’s Service shall not be deemed terminated if the Committee determines that (i) a transition of employment to service with a partnership, joint
venture or corporation not meeting the requirements of a Subsidiary in which the Company or a Subsidiary is a party is not considered a termination of Service, (ii) the Participant transfers between service as an employee and service as a
consultant or other personal service provider (or vice versa), or (iii) the Participant transfers between service as an employee and that of a non-employee director (or vice versa). The Committee may
determine whether any corporate transaction, such as a sale or spin-off of a division or subsidiary that employs a Participant, shall be deemed to result in a termination of Service for purposes of any
affected Awards. 
 12.3 No Right to Continued Service. Nothing in the Plan, in the grant of any Award or in any Award Agreement
shall confer upon any Eligible Person or any Participant any right to continue in the Service of the Company or any of its Subsidiaries, or interfere in any way with the right of the Company or any of its Subsidiaries to terminate the employment or
other service relationship of an Eligible Person or a Participant for any reason at any time. 
 12.4 Rights as Shareholder. A
Participant shall have no rights as a holder of shares of Common Stock with respect to any unissued securities covered by an Award until the date the Participant becomes the holder of record of such securities. Except as provided in Section 4.2
hereof, no adjustment or other provision shall be made for dividends or other shareholder or security holder rights, except to the extent that the Award Agreement provides for dividend payments or dividend equivalent rights. The Committee may
determine, in its discretion, the manner of delivery of Common Stock to be issued under the Plan, which may be by delivery of stock certificates, electronic account entry into new or existing accounts or any other means as the Committee, in its
discretion, deems appropriate. The Committee may require that any certificates or other evidence of ownership be held in escrow by the Company for any shares of Common Stock or cause the shares to be legended in order to comply with the securities
laws, the restrictions arising under the Plan or other applicable restrictions. Should the shares of Common Stock be represented by book or electronic account entry rather than a certificate, the Committee may take such steps to restrict transfer of
the shares of Common Stock as the Committee reasonably considers necessary or advisable. 
 12.5 Other Compensation and Benefit
Plans. The adoption of the Plan shall not affect any other share incentive or compensation plans in effect for the Company or any Subsidiary, nor 

  
 12 












 
shall the Plan preclude the Company from establishing any other forms of share incentive or other compensation or benefit program for employees of the Company or any Subsidiary. The amount of any
compensation deemed to be received by a Participant pursuant to an Award shall not constitute includable compensation for purposes of determining the amount of benefits to which a Participant is entitled under any other compensation or benefit plan
or program of the Company or a Subsidiary, including, without limitation, under any pension or severance benefits plan, except to the extent specifically provided by the terms of any such plan. 

12.6 Plan Binding on Transferees. The Plan shall be binding upon the Company, its transferees and assigns, and the Participant, the
Participant’s executor, administrator and permitted transferees and beneficiaries. 
 12.7 Additional Restrictions; Adjustments.
In the event of a change in control, a Qualified Liquidity Event or similar corporate event or a change in capital structure, the Committee shall have the power to (i) accelerate the vesting and exercisability of any Award under the Plan,
(ii) provide that outstanding Awards granted under the Plan shall either continue in effect, be assumed or an equivalent award shall be substituted therefor by the successor corporation or a parent corporation or subsidiary corporation, or
(iii) cancel, effective immediately prior to the occurrence of such event, Stock Options, Restricted Stock Unit Awards (including each dividend equivalent right related thereto), Restricted Stock Awards, and/or Other Awards granted under the
Plan outstanding immediately prior to such event (whether or not then vested or exercisable) and, in full consideration of such cancellation, pay to the holder of such Award a cash payment in an amount equal to the excess, if any, of the Fair Market
Value (as of a date specified by the Committee) of the shares of Common Stock subject to such Award over the aggregate exercise price of such Award (it being understood that, in such event, any Stock Option or Other Award having a per share exercise
price equal to, or in excess of, the Fair Market Value of a share subject to such Stock Option or Other Award may be cancelled and terminated without any payment or consideration therefor). In the event of a change in control, a Qualified Liquidity
Event or similar corporate event or a change in capital structure, any Awards that vest or become payable as a result of or in connection with the applicable event or circumstances may be subject to the same terms and conditions applicable to the
proceeds realized by the Company or its shareholders in connection therewith (including, without limitation, payment timing and any escrows, indemnities, payment contingencies or holdbacks), as determined by the Committee in its sole discretion,
subject to compliance with Section 409A of the Code. 
 13. Legal Compliance. 

13.1 Securities Laws. 

(a) No shares of Common Stock will be issued or transferred pursuant to an Award unless and until all applicable requirements
imposed by Federal and state securities and other laws, rules and regulations and by any regulatory agencies having jurisdiction, and by any exchanges upon which the shares of Common Stock may be listed, have been fully met. The Committee may in
good faith impose such conditions on any shares of Common Stock issuable under the Plan as a result of restrictions under the Securities Act or under the requirements of any exchange upon which such shares of the same class are then listed or of any
regulatory agency having jurisdiction over the Company, and under 

  
 13 












 
any blue sky or other securities laws applicable to such shares. The Committee may also require the Participant to make customary representations and warranties at the time of issuance or
transfer, including, without limitation, that the shares of Common Stock are being acquired only for investment purposes and without any current intention to sell or distribute such shares. Certificates representing Common Stock acquired pursuant to
an Award may bear such legends as the Committee may consider appropriate under the circumstances. 
 (b) From the time the
Company commences reliance on the exemption from registration provided by Rule 12h-1(f)(1) of the Exchange Act and until the Company ceases such reliance or becomes subject to the reporting requirements of
Sections 13 or 15(d) of the Exchange Act, the Company shall provide to the Award holders the information required to be delivered under Rule 12h-1(f)(1)(vi) of the Exchange Act, as applicable, in accordance
with such rule. 
 13.2 Unfunded Plan. The adoption of the Plan and any reservation of shares of Common Stock or cash amounts by the
Company to discharge its obligations hereunder shall not be deemed to create a trust or other funded arrangement. Except upon the issuance of Common Stock pursuant to an Award, any rights of a Participant under the Plan shall be those of a general
unsecured creditor of the Company, and neither a Participant nor the Participant’s permitted transferees or estate shall have any other interest in any assets of the Company by virtue of the Plan. Notwithstanding the foregoing, the Company
shall have the right to implement or set aside funds in a grantor trust, subject to the claims of the Company’s creditors or otherwise, to discharge its obligations under the Plan. 

13.3 Section 409A Compliance. To the extent applicable, it is intended that the Plan and all Awards hereunder comply with, or be exempt
from, the requirements of Section 409A of the Code and the Treasury Regulations and other guidance issued thereunder, and that the Plan and all Award Agreements shall be interpreted and applied by the Committee in a manner consistent with this
intent in order to avoid the imposition of any additional tax under Section 409A of the Code. In the event that any provision of the Plan or an Award Agreement is determined by the Committee to not comply with the applicable requirements of
Section 409A of the Code and the Treasury Regulations and other guidance issued thereunder, the Committee shall have the authority to take such actions and to make such changes to the Plan or an Award Agreement as the Committee deems necessary
to comply with such requirements. Notwithstanding anything contained herein to the contrary, a Participant shall not be considered to have terminated service with the Company for purposes of any payments under the Plan which are subject to
Section 409A of the Code until the Participant has incurred a “separation from service” from the Company within the meaning of Section 409A of the Code. Each amount to be paid or benefit to be provided under the Plan shall be
construed as a separate identified payment for purposes of Section 409A of the Code. If any payment or benefit provided to a Participant in connection with his or her separation from service is determined to constitute “nonqualified
deferred compensation” within the meaning of Section 409A of the Code and the Participant is determined to be a “specified employee” as defined in Section 409A of the Code, then such payment or benefit shall not be paid
until the day following the six-month anniversary of the separation from service or, if earlier, on the Participant’s date of death. The Company makes no representation that any or all of the payments
described in the Plan will be exempt from or comply with Section 409A of the Code. In no event whatsoever shall the 

  
 14 












 
Company or any of its Subsidiaries or Affiliates be liable for any tax, interest or penalties that may be imposed on a Participant by Section 409A of the Code or otherwise, or any damages
for failing to comply with Section 409A of the Code. 
 13.4 Tax Withholding. The Participant shall be responsible for payment
of any taxes or similar charges required by law to be paid by the Participant or withheld from an Award or an amount paid in satisfaction of an Award. Any required withholdings shall be paid by the Participant on or prior to the payment or other
event that results in taxable income in respect of an Award. In addition to the methods described in the Plan, the Award Agreement may specify the manner in which the withholding or other tax-related
obligation shall be satisfied with respect to the particular type of Award. Without limiting the foregoing, if the Company or any Subsidiary reasonably determines that under the requirements of applicable taxation laws or regulations of any
applicable governmental authority it is obliged to withhold for remittance to a taxing authority any amount upon the grant, vesting, or exercise of an Award, the other disposition or deemed disposition by a Participant of an Award or any Common
Stock or the provision of any other benefit under the Plan and if the Participant does not provide notice of the applicable withholding method from items (a) through (d) below, the Company or any of its Subsidiaries, may take any steps it
considers reasonably necessary in the circumstances in connection therewith, including, without limiting the generality of the foregoing: 

(a) requiring the Participant to pay the Company or any of its Subsidiaries such amount as the Company or any of its
Subsidiaries is obliged to remit to such taxing authority in respect thereof, with any such payment, in any event, being due no later than the date as of which any such amount first becomes included in the gross income of the Participant for tax
purposes; 
 (b) to the extent permitted, and subject to rules established by, the Committee, issuing any Common Stock issued
pursuant to an Award to an agent on behalf of the Participant and directing the agent to sell a sufficient number of such shares on behalf of the Participant to satisfy the amount of any such withholding obligation, with the agent paying the
proceeds of any such sale to the Company or any of its Subsidiaries for this purpose; 
 (c) to the extent permitted, and
subject to the rules established by, the Committee, withholding from the Common Stock otherwise issuable pursuant to the exercise or settlement of an Award a number of shares of Common Stock sufficient to satisfy the amount of any such withholding
obligation; or 
 (d) to the extent permitted by law and consistent with Section 409A of the Code, deducting the amount
of any such withholding obligation from any payment of any kind otherwise due to the Participant. 
 13.5 No Guarantee of Tax
Consequences. Neither the Company, the Board, the Committee nor any other person make any commitment or guarantee that any Federal, state, local or foreign tax treatment will apply or be available to any Participant or any other person
hereunder. 

  
 15 












 13.6 Severability. If any provision of the Plan or any Award Agreement shall be
determined to be illegal or unenforceable by any court of law in any jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their terms, and all provisions shall remain enforceable in any
other jurisdiction. 
 13.7 Governing Law. The Plan and all rights hereunder shall be subject to and interpreted in accordance with
the laws of the State of Delaware, without reference to the principles of conflicts of laws, and to applicable Federal securities laws. 
 14. Term;
Amendment and Termination. 
 14.1 Term. The Plan was first adopted by the board of directors of GulfMark Offshore, Inc.
effective as of the Effective Date. The term of the Plan will be ten years from the Effective Date, subject to Section 14.2 hereof. Upon a termination of the Plan, Awards shall remain outstanding in accordance with the terms set forth in each
applicable Award Agreement. 
 14.2 Amendment and Termination. The Board may from time to time and in any respect, amend, modify,
suspend or terminate the Plan or any Award or Award Agreement hereunder. Notwithstanding the foregoing, no amendment, modification, suspension or termination shall materially and adversely affect any Award theretofore granted without the consent of
the Participant or the permitted transferee of the Award. For purposes of this Section 14.2, any action of the Board or the Committee that in any way alters or affects the tax treatment of any award or that the Board determines is necessary to
prevent an award from being subject to tax under Section 409A of the Code shall not be considered to materially or adversely affect any Award. 

*            *           
 * 
 As amended and restated by the Tidewater Inc. Board of Directors on November 14, 2018, to be effective as of the closing of the Merger.
